The Playback panel is used to control the playback of the eye movement recording.



Selecting Play causes the tracker bar to automatically scroll from the beginning to the end of the recording at a rate determined by the Replay speed scroll bar.


The current playback time is shown within the Playback panel, an X cursor will move along each of the charts and the current playback gaze position will be indicated on the XY panel.  The current playback position of the eyes, viewing distance, horizontal and vertical PD and head tilt will be shown in the Position panel.


The eye position at a specific time can be shown by manually moving the tracker bar to the required time. 


The data can be replayed in real time by selecting the Clock icon- this then becomes Real-time replay.



Slower computers may be unable to display every data point in real-time.  If this is the case, some data points may be skipped.
